This invention-relates ,to "boxes'of theinex- 'pensive-type'lused indispensingand transporting berries and other fresh foodstuffs,'andparticularly to suchabox adapted-to bey v"eonstrusted v`frompaperboard or other-fold -able sheet material.

Itis the objectof this inventiontolprovide ainovel' andunusually strongbox fof this vkind, Vwhich is inexpensive and adapted to 'facilitateassembling and :securingifn fbox VA'form. lOther vobjects will appearand rbe fpoii'ft'e'tl out and "claims. i Y y l Y, y y f In the"accompanying v"drawings, lWhich illustrate thebest Yforniloi my device.at present knownto me, Figure lis aplan view of in the following'specification box; Figa-2 is a plan :View otthe'blankconstituting'tliebot'tom ofthe box; Fig. B jis a 251 i "be folded vThe blank ri'screased along :nor-

side"elevation of the box assembled andFig. 4 is atypical `vertical'section taken on the As shvownin Fig. A1, the inainblariklcon sists of'a rectangular sheet of paperboard or other `suitable sheet material4adapted to Lmallyverticallines i'to form ourside walls 6. At oneend,.an integral fflap -7 is formed tooverlap iand be "secured totheside6 .at oppositeendotheblank. Each ofthe sides (ibas a tongue 8,*which iisintegral with the side and adapted to be extended obliquely inward anddownward. Laterally projecting ears 9 on `each tongue 8 are adapted tosupport the bottom of the box as hereinafter described. As shown in Fig.2the bottom 10 ofthe box is also formed 4from foldable 'sheet materialand is ereased'along the dotted lines 11, to permit folding of theseries of'flanges 12 at right angles to the bottom proper, a pair ofsuch -flanges being formed on each of the four side edges. Theiiangesvof each pair are separatedby cutting an opening 18, which extends' inromaside edge ofthe blank. i f Y' The'tongues 8 are adapted to extendVinto the 'openings 13. The bottom 10 may be perforated, as indicated at14 for ventilation, and where the box is made from paper board, thematerial is treated with a moisture resistant substance, such asparaiiin.

To assemble the box, the main body Vblank is folded along the lines 5 totubular form and the end flap 7 is secured along the margin of theadjacent side 6. This fastening 'may be `made with a suitable adhesive,lsuch joint. The other normally vertical corners o'fthe box may also bereinforced lby secur-` ing stripsof` clot-h-oritoughpaper thereto. Nowthe bottom 10 of the l"box isv folded along thelinesll, 'soi thatthesevferal flanges l2extend downward, and thel bottom is placed withinthe vtubularstructure `formed `by'thesiczles 6 by' inserting it' intothe' top 15 foi' the box. *Beforepressingthe rbottom 10 down within the`box, lthe tongues 8 are bent 'obliquely inwa-rd'to substantially ftheposi,` 'tion shown inlig.l 4. Nowfthe bottomjlO is pressedidown throughythe box totheposi- 'tion i shown in: Fig; 41. The inwardly bent I'tongues 8y are passed' into thefop'er'iingsfI 1 3so thatlthe'ears 9interlock withthe jflan'ge's v12 at "each ,side of i the bottom.`,Downward movement :ofi the bottom 'is 'stopped` bythe ears '9, whichVVAof rthe openings 13.1 v:It `will' be lnoted extend 'in engagementwith `the"`inner surfaces yoi. the v sides 6, .and ythe loweredges of.said flanges are flush with' theflower; edges r.

, bottom ioajndfonttntsjare suspended@ the tongues 8. These tongues "8also constitute means for preventing outward ,bulgingl of the Asides 6when the box'is filled. It will -i thus be evident that the sides andbottom are securely'fastened togetherl in thercompleted box and theparts of the sides projecting below the bottom proper are rein- :forcedby the llanges 12 on the bottom. p lThe boxes are preferablyprepared forshippingl with the body blanks separate from the bottom panels and thebody secured in tubular form and collapsed so `as to lie Hat. `Theoperation of ass'emblingthel boxes i's'performed immediately beforetliey are filled,

10o" and Athis operation'is facilitated lby my arrangement whicheliminates all auxiliaryor y separate fastenings between the bottoms andi sides. Obviously, the voperation .of folding' the Hanges 12 andextendingy the tongues 9 into interlocking position in the openings 13may be performed quickly and easily. 'It

will further be noted that the box; has `the advantages of beingstrongandat the same time requiring a minimum ofy sheet material in itsconstruction and is, therefore, of unusually inexpensive design. Amplestrength y v is given the box byfreason of the interlock- Y ing of theears 12 with the lower surface of Y the panel l and inner surface of the{ianges 12, whereby the bottomV is positively connected with each sideof the box. i

y @Having described .my invention what 1 claim as new `and desire toprotect by Let` s ters Patent is: t Y I Y 1. In a boxl formedfroinVoldable sheet material, the combinationv witlrfour side walls, a`rectangular bottom panel vfitting Vipvithin the four walls and having adown- M wardlyprojecting langei on each side edge,

a tongue secured to aside 4wallrabove said bottom panel and projectingdownward be-V neath said bottoinpanel7 saidbottom panel being formedwith 'an opening to receive said tongue V- and means on said tongue be-'neath said bottomV panel to support the saine; f

jecting beneathsaid bottom panel, said bottom panel having an opening toreceive said c tongue and laterally projecting ears'formed on saidtongue beneath said panel to support y 3. In a box formed from, foldablesheet material, the; combination with four Vside walls, .a rectangularbottom .panel oi'setl upyjward from the lower 'edges of said'walls fandhaving a downwardly projectingflange on each side edge adapted tosupport said panel, a tongueisecuredto-.eachside wall above said bottomVpanel andprojecting downward beneath said panel, said bottom beingformed with openings to receive said tongues andinterlocking meansdisposed on each ofsaid tongues to engage the inner surfaces of saidflanges and bottom surface of said panel and thereby positively connectthe bottom panel toireach of said side walls.
